Supporting Service Owner-Controlled Placement Directives Using Cloud Services
Virtual machine placement is the process of mapping virtual machines to available physical hosts within a datacenter or on is mote datacenter in a cloud federation. Normally, service owners cannot influence the placement of service components beyond choosing infrastructure provider and deployment zone at that provider. For some services, however, this lack of influence is a hindrance to cloud adoption. For example, services that require specific geographical deployment (due e.g. to legislation), or require fault-tolerance by avoiding co-placement of critical components.
